Python application for managing resources on the data servers of the IO-SEA project. The project consists of two docker containers. The first one is the MySQL database and the second one contains the resource manager (RM) itself. SQL Alchemy and Flask-restx were used for RM development. An API interface is used to communicate with RM.
The API documentation is located in the Docs folder - Orchestrator_API.pdf
The database schema of RM.
There are three configuration files - config.txt, flavors_init.txt, servers_init.txt
config.txt - is the main configuration file. It contains the necessary information to connect to the database. There is also a setting for the API - port and IP, but it only works without using a docker container. When running via Docker, you need to edit the dockerfile. It contains the paths to the two remaining configuration files.
servers_init.txt - contains the necessary information about the available servers for resource allocation during the initial initialization of the SQL DB. Data format:
[name, max_size_RAM, free_space_RAM, min_chunk_RAM, max_size_Disk, free_space_Disk, min_chunk_Disk, max_size_CPU, free_space_CPU, min_chunk_CPU]
flavors_init.txt - contains the information about flavors. Data format:
[name, CPU_size, RAM_size, Disk_size]
logfile.log is created at the first startup in the root directory (same directory as config.txt)
The project is ready to run via Docker. Type the command to run:
docker-compose up
